Nokia's Windows Phones will start coming out at a relatively rapid clip after the first one appears later this year, Nokia's executive vice president of smart devices, Jo Harlow said today.

"We should be launching new devices in a rhythm that might be every couple of months, every three months, something like that," she said.

The first Windows Phones came out in October, and we haven't seen many devices since then. According to recent sales figures from Gartner, the phones haven't sold very well, although our Reader's Choice survey shows that the relatively few people who own Windows Phone devices love them.

The slow pace of Windows Phone hardware may be due to Windows Phone 7 being a "secondary platform" for manufacturers like HTC and Samsung, Harlow said. But as Windows will be Nokia's primary platform, Nokia will focus more heavily on Windows Phones, she said.

"We're going to keep coming with new devices in order to have something to talk about," she said.
